When To Use Data Recovery Freeware？
Data recovery freeware is an excellent idea to try in a few very specific circumstances. There are no guarantees with any commercial data recovery programs, freeware or not, however. The circumstances under which the use of freeware might be a good idea would include:
• When loss is due to human error or virus. Freeware is generally very adept at restoring files that have been accidentally deleted or damaged during a virus outbreak on a machine. Be very certain that the problem is a result of this type of issue before using, however.
• When money is at a premium. Data recovery freeware costs users nothing to try. If a good program is selected, it can have very good results and save a wallet a great deal of potential pain.
When To Avoid Using Data Recovery Freeware？
Data recovery freeware is not always the advised route to take to restore lost or damaged files. There are three particular scenarios where it can be beneficial to seek out different options. They are:
• When hardware failure is suspected. Freeware is generally designed to address software-based problems. If a mechanical crash is to blame, another route is typically advised.
• If installation is required to run the program. Good freeware recovery programs will run off the Internet or a floppy. The process of installing a program might damage all chances of recovering lost information.
• If the maker is unknown. Make sure to select data recovery freeware that is highly recommended by others. Check on computer user boards and other similar outlets before selecting a program.
Why Consider Freeware At All?
Data recovery freeware is an excellent option under the right circumstances. If files are lost due to accidental deletion or because of programming issues, these programs can work wonders. With some paid programs and professional services costing a great deal of money, many people find freeware is the best place to start. Many people start here and then work up to paid-for options if the effort doesn’t pay off with a recovery.
Which Data Recovery Freeware To Use?
The best place to look for data recovery freeware is on the Internet. A simple search should net some results. If higher recommendations are desired, try checking out computer troubleshooting web sites, message boards and other similar locations.
Data recovery freeware can provide the perfect solution to fix damaged or lost files. It does pay to tread lightly when considering this option. Sometimes the cheapest or even free option may not be the recommended route to take.
Helpful tips for using data recovery freeware
1. If your drive is making strange noises or reports a CRC read IO error, DO NOT PROCEED. This indicates a hardware failure so your data is not going to be recoverable using “undelete” style data recovery software.
2. As soon as you realize your data has been deleted, stop using the computer! The less activity the better to avoid dangerous disk-swap activity.
3. Find and download data recovery software on another computer.
4. Save the recovery tool to a flash drive and run it directly from there.
5. Save the extracted data back onto the flash drive for added safety.

Read the following tips on how to diagnose your hard drive crash and determine which recovery options are available to you. Differing causes of drive failure require differing solutions.
To find out if your drive is suffering from a physical crash or software problems, look at the lights on your hard drive. If there’s no light activity at all, or if you don’t hear or feel the disk spin inside or hear strange buzzing or different sounds than normal inside the casing, your disk crash is, in all probability, due to physical problems.
Option I: Hard Drive Boots
If you are still able to boot up your system, try booting from your recovery disk.
Many PC packages come with a disk recovery system. If you are able to boot from your recovery disk, click the START button on Windows and go on command line mode. Try running chkdisk or defrag to see if this fixes your hard drive. Oftentimes, formatting problems and disk fragmentation leads to drive crashes/corrupted disks.
After you have defragged your problematic drive, run your antivirus program and see if it cleans out any viruses. In many situations, viruses can corrupt your operating system or key drivers leading to system crashes. See if this takes care of the problem.
If your data is located in undamaged folders, copy them onto a CD or USB drive and make a list of all your applications. Make sure you know where to download your applications or where you stored the original copy.
If you cannot find your data, or it was stored in a corrupted location, don’t panic! To recover your data, try one of the many data recovery softwares available on the Internet today. These software packages help you restore your disk partitions, folder structure, or even recreate folders so you can find and recover your data.
If you cannot recover your data with data recovery software, skip to options III. Make sure to exhaust all your options before you go and seek professional help since professional data recovery assistance can come with a hefty price tag.
Once you have your data and your applications ready for reinstallation, “wipe” your disk and reinstall your OS. Make sure that your OS is patched with all its current updates.
Option II: Hard drive doesn’t boot but the drive still has blinking lights.
In this situation, plug in a spare working hard drive into a USB port or on a vacant controller slot on your motherboard. In the case of inserting a new master drive into your desktop PC’s chassis, make sure you rearrange the controller jumper on the main board so that it recognizes the new master / slave settings of your hard drives. Upon boot up, get into the boot settings of your computer and set up the new drive as the MASTER and the non-booting drive as the SLAVE.
Once you’ve booted, run your recovery disk and run chckdisk/fdisk and defrag on your slave disk. Follow the rest of the steps and options outlined in Option I above.
Option III: Hard drive is physically damaged!
If your drive has physically crashed, you may still be able to recover your data, even if physical damage has occurred.
Physical hard drive damage usually involves problems with the disk motor or the disk reading head is physically misaligned and fails to work. Sadly, physical damage often means that some of your data might be permanently lost. Just because your hard drive has suffered physical damage, don’t automatically assume that the only solution left is to go seek professional help. Try the tips below first before seeking professional data recovery.
Can you still boot but your PC is really slow? If this is the case, install and use data recovery software to isolate your data and load it onto a storage device like a USB stick. Once you have archived your data and make an inventory of your installed applications, take out the drive and replace it with a new drive.
Does your hard drive make a weird noise? Strange noises are indicative of hardware problems. However, if your drive still works regardless of the noise, install and use data recovery software to find and move your data before you replace your drive.
If none of the options above don’t apply, it is time to seek professional data recovery assistance. Professional data recovery services are not cheap. The cost goes up based on the amount of data you want recovered. Since this situation involves the outlay of substantial amounts of money, here’re some tips to help you select the right data recovery company.
Tips for finding the right data recovery companies:
In closing, a hard drive crash, as traumatic as it can be, is not a death sentence. Make sure you are aware of your do it yourself and professional data recovery options. Keep the options above so you can save time and money. One final note: always remember to back your data up either yourself or by using a data backup software. Do it early. Do it often. Just Do It!
